D50D series unable to RDP to win 10 workstations

I've tried the firmware from 2016 and the newest firmware from 2017 on the D50D units and I'm unable to get a RDP session to complete to a Windows 10 Workstation.

I have no problems getting the RDP to work with Server 2012 R2 RDS, but, even using NLA, I can't get the Wyse to RDP into a Win 10 Workstation.

I checked the firmware PDF online and it doesn't show testing/support for Win 10, but we can still buy these units and they are still under warranty...

Anyone found a  way to connect a D50D to a Windows 10 Workstation using RDP?
